getkeycreatecon(3) SELinux API documentation getkeycreatecon(3)
getkeycreatecon, setkeycreatecon - get or set the SELinux security
context used for creating a new kernel keyrings
#include <selinux/selinux.h>
int getkeycreatecon(char **con);
int getkeycreatecon_raw(char **con);
int setkeycreatecon(char *context);
int setkeycreatecon_raw(char *context);
getkeycreatecon() retrieves the context used for creating a new
kernel keyring. This returned context should be freed with
freecon(3) if non-NULL. getkeycreatecon() sets *con to NULL if no
keycreate context has been explicitly set by the program (i.e. using
the default policy behavior).
setkeycreatecon() sets the context used for creating a new kernel
keyring. NULL can be passed to setkeycreatecon() to reset to the
default policy behavior. The keycreate context is automatically
reset after the next execve(2), so a program doesn't need to
explicitly sanitize it upon startup.
setkeycreatecon() can be applied prior to library functions that
internally perform an file creation, in order to set an file context
on the objects.
getkeycreatecon_raw() and setkeycreatecon_raw() behave identically to
their non-raw counterparts but do not perform context translation.
Note: Signal handlers that perform a setkeycreatecon() must take care
to save, reset, and restore the keycreate context to avoid unexpected
behavior.
Note: Contexts are thread specific.
On error -1 is returned. On success 0 is returned.
